To all whom c't may concern:

Be it known that I, EDWARD M. Bnoons, a subject of he King of Great Britain, and resident of Fort lVayne in the county of Allen and State of indiana, have invented certain new and useful Improvements in Window-Fasteners, of which the following is a specification.

This invention relates to improvements in window fasteners and the object thereof is to provide a device of its class adapted to secure windows in a manner to prevent opening movement thereof being applied from the exterior, and which will be effective at all positions of the window.

The object of the invention is accomplished by the construction illustrated in the accompanying drawings in which:

figure 1 is a perspective view showing the invenion applied to a pair of window sashes of the usual type;

Fig. 2 is a detail perspective view of one of the ratchet members;

Fig. 3 is a perspective view of the supporting bracket for the ratchet member;

Fig. i is an end view of the ratchet member mounted in connection with its supporting: bracket, there being parts broken away and in section;

Fig. 5 is an elevation showing portions of a pair of window sashes with the invention applied thereto; and

Fig". 6 is a another view of the ratchet member showing across section through its hub and the rod upon which it ismounted.

Similar numerals of reference indicate corresponding parts throughout the several views and referring now to the same:

1 and 2 are upper and lower sashes of a window of usual construction adapted to be raised and lowered. 3 are notched bars that are fitted into the inner faces of the upper sash 1 respectively at the sides thereof. Upon the top of the sash 2, at each side thereof is mounted a bracket 4, and in each bracket is mounted a rachet member 5 having a hub 6 that extends through an opening 7 in the bracket. A slot 8 is made in the hub of the ratchet member and a screw 9 in the bracket extends into the slot 8 in the hub of the bracket so that the ratchet is loosely secured. A rod 10 is connected at its respective ends in the hubs 6 of the corres ponding brackets, there being a pin 11 extending through each hub and engaging the rod so that as one ratchet member is turned upon its axis, the other ratchet member will likewise be turned. The pin 11 extends loosely through an opening 10 in the rod 10 so as to admit of slight play between the rod and 'atchet, the purpose being to permit the ratchet suthcient freedom as to inde pendently engage the notches of the corresponding bars.

The bracket d has a projection 12 at its outer end having a pair of caviti s 13 made in the upper face thereof, and "he ratchet meml er 5 has pocket which contains a spring 15 and 3211i 16. The spring acts against the ball tending to press it against the projection 1.1, so that as the rachet is turned upon its hub the ball will become pressed into one or the other of the cavities 13 and tend to hold the ratchet in position accordingly. Thus, when the ratcl'iets are moved into engagement with the notched bars 3 the ratchets tend to remain engaged therewith, because of the tendency of the spring pressed balls to remain engaged in the cavities. Likewise when the ratchets ar moved out of engagement with the notched bars and the balls become shifted so as to engage the opposite cavities and the ratchets are thereby held from engaging the notched bars.

In using; the invention the window sashes are secured by manipulating one or the other of the ratchets so as to engage its notched bar which has the eiiect, because of the connection of the rod 10, of likewise moving the other ratchet into engagement with its corresponding notched bar. When the ratchets are thus positioned, the upper sash may be moved upwardly or the lower sash may be moved downwardlv until the window is completely closed. But, because of the engagement of the ratchet-s which are mounted on the lower sash with the notched bars which are mounted upon the upper sash,

the opening); movement of either sash relative to the other s prevented. By manipulatmg either one or the other of the ratchets both may be disengaged from the notched opening movement of one sash relative to bars and thus permit free movements oi the the other; and means 111 connection with sashes. eaeh ratchet to hold the same in engaging What I claim is: and disengaging pesitiens.
